color beneath on the flanks, the colors unite in such a way as to leave a series of dark trian- 
gular marks, giving it a serrated appearance ; these serratures are continued to the tip of the 
tail, and become effaced towards the head. In adults, the abdomen for the most part imma- 
culate ; in the young, a minute dark point on the middle of the edge of every abdominal 
plate, as far as the vent.

This pretty little snake is found in every part of the State. It occurs under rocks and 
stones, and is frequently seen under the bark of decayed trees. It is very common under the 
bark coverings of the huts of the frontier settlers. Feeds upon worms, insects, grubs, etc., 
and is perfectly inoffensive. Emits a strong and disagreeable odor. Occurs from Maine to 
Louisiana.

This innocent and beautiful species, known in this State as the Green or Grass Snake, 
has long been confounded with the estivus of the Southern States, from which it is readily 
distinguished by its inferior length and carinate scales. It feeds on insects, and is exceed- 
ingly lively and quick in its movements. It is very numerous in the marshes about Salina 
and Cayuga; and, as I have been informed by credible eye-witnesses, fights furiously with 
the Striped Snake previously described. Its color changes upon immersion in alcohol, from 
a brilliant green to a dull blue. I am inclined to suspect, that in this State, it has been
